Donald Trump congratulated Boris Johnson on election win in phone call

US President Donald Trump has spoken to Boris Johnson to congratulate him on his general election victory, Downing Street has said.

A No.10 spokesman said in the course of the telephone call, the two leaders discussed their wish to secure an "ambitious" free trade agreement once Britain has left the EU.

"The Prime Minister spoke with President Trump, who congratulated him on the result of the General Election," the spokesman said.

"They discussed the huge importance of the relationship between the UK and US, and looked forward to continued close co-operation on issues such as security and trade, including the negotiation of an ambitious free trade agreement."

When he came to London for the 70th anniversary meeting of Nato leaders at the start of December, Mr Trump also insisted that he had no interest in the UK health service.

Mr Trump had already weighed into the campaign once, urging Mr Johnson to form a pact with Nigel Farage's Brexit Party - and warning that Jeremy Corbyn would be "so bad" for the UK as prime minister.
